Description

BACKGROUND OF THE INVENTION
This invention relates to substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans, cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes and uses thereof in augmenting or enhancing the aroma of perfume compositions, perfumed articles and colognes.
Balsamic, piney, sweaty, animalic, woody, ambery, fruity, musky, tobacco-like, sweet, apple-like, lactonic and coumarin-like aromas, with piney, ozoney, balsamic, herbaceous, buttery, ambery, orris-like, woody, plum-like, sweaty and animalic topnotes and "air dried clothing" undertones are particularly desirable in augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles (e.g., solid or liquid, anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, hair preparations, cosmetic powders and perfumed polymers).
Compounds having the oxabicyclooctane nucleus have been known for use in augmenting or enhancing the aroma of perfume compositions, perfumed articles and colognes for a number of years. Thus, the compound having the structure: ##STR2## is disclosed at column 4, lines 35-40 of U.S. Pat. No. 4,269,862 (Sprecker, et al, II) to have a minty, camphor, woody and piney aroma profile. U.S. Pat. No. 4,269,862 further discloses the genus defined according to the structure: ##STR3## wherein R1 is hydrogen or methyl and R2 is C3 -C5 alkyl or alkenyl to have utility in augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles.
Furthermore, cineole itself having the structure: ##STR4## is disclosed by Arctander "Perfume and Flavor Chemicals" (Aroma Chemicals), at monograph 616 to have a eucalyptus aroma (its common name is "eucalyptol").
U.S. Pat. No. 5,081,262 issued on Jan. 14, 1992 discloses substituted cyclopentenyl oxabicyclooctanes, cyclopentenylformylcyclohexenes and cyclopentenylhydroxymethyl cyclohexenes, processes for preparing same and organoleptic uses thereof. The oxabicyclooctane derivatives, the cyclopentenylformylcyclohexenes and cyclopentenylhydroxymethyl cyclohexenes of U.S. Pat. No. 5,081,262 have the generic structures: ##STR5## wherein R1, R2, R3 ' and R3 " each represents hydrogen or methyl with the provisos:
(i) one or two of R1, R2, R3 ' and R3 " is methyl;
(ii) R1 and/or R2 is methyl;
(iii) at least one of R3 ' and R3 " represents hydrogen; and
(iv) when R1 and R2 are both methyl then each of R3 ' and R3 " each represent hydrogen.
Nothing in the prior art, however, discloses the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans, cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention or their organoleptic uses.

Thus, polymer (e.g., polyolefin) added to the container 212 is heated from 10-12 hours whereafter a scent or aroma imparting material which contains or consists of at least one of the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention is quickly added to the melt. The material must be compatible with the polyolefin and forms a homogeneous liquid melt therewith. The scented material containing or consisting or at least one of the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention is of a type for the particular aroma desired and formulated specifically for the scenting purpose for which the polyolefin will be employed. The aromatic materials in some instances in solid or powdered form may be employed or added to the polyolefin in the container 212. Generally about 10-30% by weight of the scenting material is added to the polyolefin.
After the scent imparting material containing or consisting of at least one of the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention is added to the container 212, the mixture is stirred for a few minutes, for example, 5-15 minutes and maintained within the temperature ranges indicated previously by the heating coils 212A and 218, respectively. The controls 216 and 220 are connected through cables 224 and 226 to a suitable supply of electric current for supplying the power for heating purposes. The controls 216 and 220 are connected to the heating coils 212A, respectively, through wires 214 and 222.
Thereafter, the valve "V" is opened permitting the mass to flow outwardly through conduit 232 having a multiplicity of orifices 234 adjacent to the lower side thereof. The outer end of the conduit 232 is closed so that the liquid polymer (e.g., polyolefin) and aroma imparting material mixture (containing or consisting of at least one of the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention) will continuously drop through the orifices 234 downwardly from the conduit 232. During this time, the temperature of the polymer (e.g., polyolefin) containing an aroma mixture containing or consisting of at least one of the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention in the container 212 is accurately controlled so that a temperature in the range of from about 210°-275° F. will exist in the conduit 232. The regulation of the temperature through the control 216 and the control 220 is essential in order to insure temperature balance to provide for the continuous dropping or dripping of molten polymer (e.g., polyolefin) and scenting material containing or consisting of at least one of the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention through the orifices 234 at a rate which will insure the formation of droplets 236 which will fall downwardly onto a moving conveyor belt 238 trained to run between conveyor wheels 240 and 242 beneath the conduit 232.
When the droplets 236 fall onto the conveyor 238, they form pellets 244 which harden almost instantaneously and fall off the end of the conveyor 238 into a container 245 which is advantageously filled with water or some other suitable cooling liquid in order to insure the rapid cooling of each of the pellets. The pellets 244 are then collected from the container 245 and utilized in a process as illustrated, infra.
A feature of this aspect of the process of our invention is in the provision for moistening the conveyor belt 238 to insure rapid formation of the solid polymer (e.g., polyolefin)-scented pellets 244 without sticking to the belt. The belt 238 is advantageously of a material which will not normally stick to a melted plastic but the moistening means 248 insures a sufficiently cold temperature of the belt surface for the adequate formation of the pellets 244. The moistening means comprises a container 250 which is continuously fed with water 254 to maintain a level for moistening a sponge element 256 which bears against the exterior surface of the belt 238.
Thus, a perfumed polymer consisting of a microporous polymer (e.g., polyethylene) is created which has intimately admixed therewith in the interstices thereof an aroma augmenting, enhancing or imparting quantity of at least one of the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention.
THE INVENTION
The instant invention provides substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes defined according to the generic structures: ##STR47## wherein R1, R2, R', R", R1 ', R2 ', R1 " and R2 ", are the same or different and each represents hydrogen or methyl with the provisos that:
(i) R1 and R2 are not both methyl;
(ii) R' and R" are not both methyl;
(iii) when R1 ' is methyl, then R2 ' is hydrogen; and
(iv) when R2 " is methyl, then R1 " is hydrogen.
The substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention are useful in augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles (including but not limited to solid or liquid, anionic, cationic, nonionic or zwitterionic detergents, perfumed polymers, fabric softener compositions, fabric softener articles, cosmetic powders, hair preparations and the like).
Briefly, our invention also employs the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention to impart, augment and/or enhance balsamic, piney, sweaty, animalic, woody, ambery, fruity, musky, tobacco-like, sweet, apple-like, lactonic and coumarin aromas, with piney, ozoney, balsamic, herbaceous, buttery, ambery, orris-like, woody, plum-like, sweaty and animalic topnotes and "air dried clothing" undertones in or to perfume compositions, colognes and perfumed articles (e.g., solid or liquid, anionic, cationic, nonionic or zwitterionic detergents, perfumed polymers, fabric softener compositions, fabric softener articles, hair preparations, cosmetic powders and the like).
Briefly, the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention may be prepared by first forming a compound having the structure: ##STR48## by means of hydrogenating a compound having the structure: ##STR49## with hydrogen using, for example, a palladium on carbon catalyst according to the reaction: ##STR50## The product having the structure: ##STR51## is then reacted with formaldehyde according to the reaction: ##STR52## in order to produce the compound having the structure: ##STR53## The compound having the structure: ##STR54## is then reacted with a diene/dienophile having the structure: ##STR55## according to the reaction: ##STR56## wherein R is hydrogen or methyl and R1 and R2 are the same or different hydrogen or methyl. When this reaction is carried out a side product is formed also having good organoleptic utilites defined according to the generic structure: ##STR57## wherein R' and R" are the same or diffferent hydrogen or methyl. R' and R", in separate compounds in the mixture are each methyl when R is methyl. The compound having the structure: ##STR58## is formed under a mechanism where the compound having the structure: ##STR59## acts as a dienophile and the compound having the structure: ##STR60## acts as the "diene".
The resulting compounds having the structure: ##STR61## are then reduced according to the reaction: ##STR62## whereby compounds defined according to the structure: ##STR63## are formed. Again, when R is hydrogen, then R1 and R2 are each hydrogen; and when R is methyl, a mixture is formed where one of R1 or R2 is methyl in one of the compounds of the mixture and the other of R1 or R2 is methyl in the other of the compounds of the mixture.
The resulting compounds have the structure: ##STR64## are then caused to be cyclized to form compounds having the structures: ##STR65## according to the reaction: ##STR66## having the reaction mechanism: ##STR67## It should be noted, that when R1 or R2 are methyl, the carbon having the methyl group (carbon atom "3" or carbon atom "4") is more electrophilic and nucleophilic attack of the oxygen of the hydroxyl moiety takes place at the most electrophilic carbon atom. Hence, in the mixture of compounds having the structures: ##STR68## when R1 ' is methyl then R2 ' is hydrogen and when R2 " is methyl, R1 " is hydrogen and in such case, R1 " is always hydrogen and R2 ' is always hydrogen.
With respect to each of the reactions set forth above whereby compounds having the structures: ##STR69## are produced, at the end of each of the reactions, the reaction products can be used as is for a subsequent reaction or the reaction products can be used for their organoleptic properties (and thus fractionally distilled).
Starting with the production of the compounds having the structures: ##STR70## the reaction sequences; that is, the Diels-Alder reaction, the alcohol formation reactions and the cyclization reactions are carried out using the conditions substantially the same as those set forth in U.S. Pat. Nos. 4,269,862 and 4,267,067, the specifications for which are incorporated by reference herein. The conditions set forth in the above stated U.S. Pat. Nos. 4,269,862 and 4,267,067 are for the reaction schemes: ##STR71## and said conditions are set forth at column 5, lines 50-68; column 6, lines 1-62; column 7, lines 1-68 and column 8, lines 1-34 of U.S. Pat. No. 4,269,862 as well as column 5, lines 41-68; column 6, column 7 and column 8, lines 1-29 of U.S. Pat. No. 4,267,067.
Thus, the Diels-Alder reaction of the aldehyde having the structure: ##STR72## with the conjugated diene having the structure: ##STR73## is, in general, a procedure known in the prior art. The reaction may be carried out in the presence of Lewis acid catalysts such as zinc chloride, aluminum chloride or aluminum bromide; or it may be carried out in the absence of catalysts at higher temperatures, e.g., up to 200° C. When carrying out the Diels-Alder reaction in the presence of catalysts, lower temperatures, e.g., -10° C. up to 30° C. may be utilized. The Diels-Alder reaction may be carried out in the presence of or in the absence of a solvent. When solvents are used it is preferred to use such solvents as xylene or tetralin.
The reaction of the cyclohexene carboxaldehyde to form the cyclohexene carbinol followed by cyclization may take place in a single reactor without separation of the cyclohexene carbinol or may take place in two separate reactors with separation of the cyclohexene carbinol followed by cyclization.
When carrying out that part of the reaction sequence whereby the cyclohexene carboxaldehyde defined according to the structure: ##STR74## is reduced to form the compounds defined according to the structure: ##STR75## according to the reaction: ##STR76## the reaction takes place in the presence of a solvent such as isopropenol, tetrahydrofuran, dioxane, diethyl ether, or diglyme using a reducing agent such as sodium borohydride, lithium aluminum hydride or VITRIDE® (registered trademark for the compound having the structure: ##STR77## of the Hexcel Company).
The reaction: ##STR78## the "cyclization reaction" takes place using a cyclization reagent such as methane sulphonic acid or sulfuric acid.

______________________________________
At least one of the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention and one or more auxiliary perfume ingredients including, for example, alcohols (other than the alcohols of our invention), aldehydes (other than the aldehydes of our invention), ketones, terpenic hydrocarbons, esters, lactones, ethers (other than the cyclic ethers of our invention), natural essential oils and synthetic essential oils may be admixed so that the combined odors of the individual components produce a pleasant and desired fragrance, particularly and preferably in the balsamic and pine fragrances. Such perfume compositions usually contain (a) the main note or the "bouquet" or foundation stone of the composition; (b) modifiers which round off and accompany the main note; (c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation and substances which retard evaporation; and (d) topnotes which are usually low boiling fresh smelling materials.
In perfume compositions, it is the individual components which contribute to their particular olfactory characteristics, however, the over-all sensory effect of the perfume composition will be at least the sum total of the effects of each of the ingredients. Thus, at least one of the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention can be used to alter, modify or enhance the aroma characteristics of a perfume composition, for example, by utilizing or moderating the olfactory reaction contributed by another ingredient in the composition.
The amount of one or more of the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention which will be effective in the perfume composition as well as in the perfumed articles and colognes depends on many factors including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little as 0.01% of at least one of the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention or even less (e.g., 0.005%) can be used to impart, augment or enhance balsamic, piney, sweaty, animalic, woody, ambery, fruity, musky, tobacco-like, sweet, apple-like, lactonic and coumarinic aromas with piney, ozoney, balsamic, herbaceous, buttery, ambery, orris-like, woody, plum-like, sweaty and animalic topnotes and "air dried clothing" undertones to soaps, cosmetics, solid or liquid, anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, hair preparations and perfumed polymers. The amount employed can range up to 70% of the fragrance components and will depend on considerations of cost, nature of the end product, the effect desired on the finished product and the particular fragrance sought. In fact, as much as 100% of the fragrance component can be the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention in certain specific instances, e.g., the formation of specific perfumed polymers on an industrial level.
One or more of the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention are useful (taken alone or together with other ingredients in perfume compositions) as (an) olfactory component(s) in detergents and soaps, space odorants and deodorants, perfumes, colognes, toilet water, bath preparations such as creams, deodorants, hand lotions and sun screens; powders such as talcs, dusting powders, face powders and the like. When used as (an) olfactory component(s) as little as 1% of at least one of the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention or even less will suffice to impart intense and substantive balsamic, piney, sweaty, animalic, woody, ambery, fruity, musky, tobacco-like, sweet, apple-like, lactonic, and coumarin-like aromas, with piney, ozoney, balsamic, herbaceous, buttery, ambery, orris-like, woody, plum-like, sweaty and animalic topnotes with "air dried clothing" undertones to pine formulations and xobalsamic formulations. Generally, no more 20% of at least one of the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention based on the ultimate end product is required in the perfume composition; however, perfume compositions can in their entireties in certain specific instances only contain the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention.
Accordingly, in perfume compositions and colognes from about 0.01% up to about 100% of the perfume composition may be at least one of the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexenes of our invention. In perfumed articles, the quantity of at least one of the substituted cyclopentyl oxabicyclooctanes, cyclopentyl vinyl pyrans cyclopentylformylcyclohexenes and cyclopentylhydroxymethyl cyclohexene of our invention in a perfumed article may vary from about 0.005% up to about 25% of the perfumed article.
